Removal of pharmaceutical compounds commonly-found in wastewater through a hybrid biological and adsorption process.

Nowadays, alternative options to conventional wastewater treatment should be studied due to rising concerns emerged by the presence of pharmaceuticals compounds (PhCs) in the aquatic environment. In this work, a combined system including biological treatment by activated sludge plus adsorption with activated carbon is proposed to remove three selected drugs […]

Estudio de los problemas de bioensuciamiento de membranas y espumas de origen biológico en sistemas MBR de tratamiento de lixiviados.

Los biorreactores de membrana (MBR) se incluyen en las denominadas tecnologías de membrana, las cuales han experimentado un gran desarrollo en la última década. La aplicación de estas tecnologías permite la separación del licor de mezcla y el agua depurada mediante membranas (UF ó MF), obteniendo ventajas importantes frente a […]

Changes in the process performance, sludge production and microbial activity in an activated sludge reactor with addition of a metabolic uncoupler under different operating conditions.

Sludge production in wastewater treatment plants is nowadays a big concern due to the high produced amounts and their characteristics. Consequently, the study of techniques that reduce the sludge generation in wastewater treatment plants is becoming of great importance. In this work, four laboratory sequencing batch reactors (SBRs), which treated […]

DESASS: A software tool for designing, simulating and optimising WWTPs.

This paper presents a very useful software tool to design, simulate and optimise wastewater treatment plants. The program is called DESASS (DEsign and Simulation of Activated Sludge Systems) and has been developed by CALAGUA research group. The mathematical model implemented is the Biological Nutrient Removal Model No.1 (BNRM1) which allows […]
